FRUIT-JAB-COVEE FASTENER AND REMOVEB.

Application an August 19, 1919. Serial m. 318,517.

To all whom it may concern:

' Be it known that we, CRELLAN GRANT OVERBAUGH and FRANKFIQELL, both sub'ects of the King of Great Britain, and resi cuts 6 of the town of Port Rowan, county of N orfo1k, lProvin'ce of Ontario, in the ominion of Canada, have invented certain new and usefulv Improvements in a Fruit-J'arCoVer Fastener and Remover, described in the following specification and illustrated in the accompanying drawings, that form part of the same. I

Among the objects of the invention are, to provide a device which will facilitate the handling of fruit jar covers, particularly of v the screw top type called Mason jar covers which frequently use an external compressible ring, and to provide a device of such character which is very simple inconstruction and yet' very effective for the purpose set forth.

The principal feature of the invention consists in the novel construction of device whereby a circular convergin surface is 25 presented to engage and grip t e jar cover.

any gripping devices inthe form of clamps of various kinds have, been devised for the purpose of securing or loosening fruit jar covers but most of such devices have proved unsuccessful in that the covers are inj uredby the device and the present invention overcomes this difliculty.

In the drawings 'Figure 1 is a sectional elevational view of the, preferred form of this invention showing the manner of gripping the. jar cover or screw top. Y

Flgure 2 is a sectional elevational view showing the manner of releasing the cover from the device.

Figure 3 is a sectional elevational view of a modification of the device.

The device shown in Figures 1 and 2 com-' smooth conical inner wall an The cup or'cap-shaped member is fastened upon the wall or the underside of a table or shelf or it'may be placed on top of a table if desired and is simply secured by the screws 4 which pass through holes in the top. In ,using the device, the jar, upon which the cover has been secured fairly tight with the hands, is held in the hands and the cover,

is inserted into the device until the upper edge of the cover engages the taper snugl The jar is then turned and the slight y tapered surface of the cup grips theouter circumference of the cover and holds it securely while the jar is screwed tightly into the cover. The loosening of the cover is accomplished in the reverse manner.

In order to release the cover it is merely in Fig. 2 and it immediately releases from the ripping contact.

Tfie device may be formed in several ways, one modification being shown in Figure .3 in which the tapered ring 5 is merely flanged outward at the smaller end and the fastening screws are inserted through the flange 6.

It will be ilnderstood quite readilythat the gripping efi'ect is uniform all around the cover, consequently there is no tendency to distort it and further, the gripping occurs at the strongest part-0f the cover, that is, at the threaded portion 8.

What we claim as our invention -is:-

1. A fruit-jar cover fastener and remover, comprising acircular member havin a smooth plane conical surface adapted to icadapted to be secured to a rigid structure.

3. A fruit-jar cover fastener and remover, comprising a sheet-metal on having a screw-holes in the top thereof. 7
